Electronic devices that include batteries can be adapted to provide one or
more indications of a low battery condition. An electronic device such as
a controller can include a battery and can be adapted to determine a
first low battery condition. A first indication can be provided in
response to the first low battery condition. In some cases, a second
battery condition can be determined and a second indication can be
provided in response to the second battery condition. The indications
provided to the user can be made progressively more noticeable over time,
until the battery is replaced.
